Description

  The present invention relates to a mattress formed by connecting a large number of coil springs to form a spring unit, and covering the entire spring unit with an exterior body, and a method for manufacturing the same. Here, the mattress includes a legged mattress fixed on a base supported by legs, in addition to those constituting the product as a single unit.

  Conventionally, as this type of mattress, the one shown in Patent Document 1 is known. That is, a large number of coil springs are connected and fixed to constitute a spring unit, covered with an exterior body (side cloth), and fixed to the base.

However, in the conventional technology as described above, in order to produce a bed that gives the user a comfortable sleeping feeling, the structure and arrangement of the spring unit are changed, or a cushioning material is inserted into the upper layer of the spring unit. The mattress structure itself had to be changed, and there was a problem that it was not easy to make an optimal selection according to the physique and weight.
In addition, users who place importance on interior properties do not like changing the appearance of the bed (especially the thickness of the mattress), and may have sacrificed sleeping comfort.

  In addition, in the mattress with legs, the manufacturing process can be simplified because the mattress is generally installed directly on the base, but since the mattress inherent to the base is used, the sleeping comfort is appropriately changed according to preference. However, there was a problem that the selection was more difficult and selection was limited.

  The present invention solves such a conventional problem by changing only the wire diameter of the coil spring, and without changing the appearance and structure of the mattress according to the user's physique, weight and preference. An object of the present invention is to provide a mattress capable of selecting a desired sleeping comfort and a method for manufacturing the mattress.

  According to the mattress and the manufacturing method thereof according to claims 1 and 2 of the present invention, it is possible to adjust the desired repulsive force without changing the configuration other than the coil spring, and to obtain the user's favorite sleeping comfort, The process can also be simplified.

  In addition, according to the mattress with legs and the manufacturing method thereof according to claims 3 and 4, the user's favorite sleeping comfort can be obtained by adjusting to a desired repulsive force without changing the configuration other than the coil spring. The process can be simplified, and more options can be provided to the user without sacrificing the design or the like.

Hereinafter, an embodiment that represents the present invention will be described with reference to the drawings.
1 to 5 show an embodiment of the present invention.
As shown in FIG. 1, the legged mattress 1 according to the embodiment of the present invention is configured such that the spring unit 11 is placed on the upper surface of the base 20 and the upper and side surfaces of the spring unit 11 are covered with the side fabric (exterior body) 15. The side edge of the side fabric 15 is fixed to the base 20. Hereinafter, although the mattress 1 with a leg is demonstrated, it cannot be overemphasized that the mattress itself except the base 20 may be sufficient.

As the side fabric 15, a material having good touch such as cotton is used. The method of fixing the side fabric 15 to the lower surface of the base 20 may be constituted by a removable material such as a cotton fastener.
The base 20 is obtained by attaching a leg 25 to an appropriate position below a rectangular substrate by a normal fixing means such as a screw. The legs 25 are made of a material such as wood, steel, or chrome.

  The spring units 11 are arranged at predetermined intervals in the horizontal direction with the coil springs 10 extending and contracting up and down, and upper and lower end surfaces thereof are connected to a helical wire 14 or a frame line 5 that determines the shape of the spring unit. Further, the entire upper and lower surfaces are covered with a cushioning material (felt 12 and urethane foam 13), and the entire surface is covered with an interior sheet 17 made of a nonwoven fabric or the like. The urethane foam 13 may have a low resilience specification.

  Further, as shown in FIG. 3, a pocket coil 16 may be used as the coil of the spring unit 11. The pocket coil 16 is the one in which the coil spring 10 is housed in a cylindrical bag and is densely arranged in the horizontal direction in the direction of expanding and contracting up and down, and the adjacent springs are not connected by the helical wire 14 or the like. It provides a comfortable sleeping experience that stretches and contracts with the body shape of the user.

  The arrangement of the pocket coils 16 may be arranged in parallel as shown in FIG. 5 (a), or may be arranged alternately as shown in FIG. 5 (b). In particular, when alternately arranged, the body shape is more closely fitted, so that the sleeping comfort is further enhanced.

Next, the operation will be described.
FIG. 2 shows a legged mattress in which the wire diameter of the Bonnell-coil type legged mattress 1 according to the present embodiment is changed to a thicker one.
FIG. 4 shows a legged mattress in which the wire diameter of the pocket coil type mattress 1A according to the present embodiment is changed to a thicker one.

  According to the legged mattress 1 according to the embodiment of the present application, the coil spring 10 is appropriately selected from a plurality of types of prepared coil springs. Thereby, the manufacturing process can be simplified without changing the design of other configurations, and various variations of mattresses with legs and mattresses 1 with legs can be provided.

  That is, in the manufacturing process, the coil spring 10 is selected from a plurality of types prepared and used. Here, the coil spring 10 includes, for example, a thin wire diameter shown in FIG. 1 and a thick wire diameter shown in FIG. Of course, the present invention is not limited to these two types, and three or four or more coil springs 10 having different wire diameters may be prepared.

  The thicker the wire diameter of the coil spring 10, the greater the compressive load. Therefore, the overall feel on the surface of the legged mattress 1 becomes harder. On the contrary, as the wire diameter of the coil spring 10 is thinner, the compressive load is reduced, so that the feel on the surface of the legged mattress 1 is softened as a whole.

  The mattress 1 is usually of a bonnel coil type and a pocket coil type. In the case of the bonnel coil type, the coil spring 10 is connected to the frame wire 5 to the helical wire 14 and arranged at the stage of manufacturing. By arranging the coil spring 10 having a desired repulsive force corresponding to the user's preference, it is possible to manufacture a mattress that can obtain the user's preferred sleeping comfort.

  In addition, in the pocket coil type mattress 1A with legs, the mattress which can obtain the user's favorite sleeping comfort by placing the coil spring 10 having a predetermined repulsive force placed in a bag in the frame 5. Can be manufactured.

  It is possible to easily manufacture a mattress that can obtain the user's favorite sleeping comfort without changing the configuration other than selecting the coil spring 10 selectively. At that time, it is not necessary to insert a cushioning material or change the arrangement of the coil spring 10.

  The embodiments of the present invention have been described above with reference to the drawings. However, the specific configuration is not limited to the above-described embodiments, and the present invention can be changed or added without departing from the scope of the present invention. Included in the invention. For example, in the said embodiment, although the buffer material was made with the nonwoven fabric (felt) 12 and the urethane foam 13, you may use a palm material, coco fiber, etc. instead of or in addition to the nonwoven fabric 12.

  Moreover, in the said embodiment, although arrangement | positioning of the coil spring was not described especially in the Bonnell coil type, you may make a sparse part in arrangement | positioning of a spring according to arrangement | positioning of a body. The coil spring near the center where it can easily sink may be used densely or with a large repulsive force.

  Furthermore, you may use for the buffer material and the exterior body 15 what has a deodorizing effect, an antibacterial effect, and a tick-proof effect. Although the type of the coil spring is not particularly described, a progressive spring, a drum coil spring, or a barrel coil spring may be used in addition to a normal cylindrical isometric coil spring.
